(Is Schicht claiming that the published composition in 1814 was partially - the Gloria and Credo - by him, perhaps Fux' music for those two sections had gone missing? - Schissel, who should just run that through a translator... hrm. ...!! )

The Prague copy has a part for violone, so not all copies are for unaccompanied chorus only. (This could be spurious/editorial addition...) This copy gives the dedicatee of the work as Karl VI, Roman-German Emperor.
